The OPxl77 family of operational amplifiers offers high precision, low noise, and low input bias current, making them suitable for a wide range of applications.

Key Features

Low offset voltage (60 uV maximum), low offset voltage drift (0.7 uV/°C maximum), and low input bias current (2 nA maximum).

Low noise (8 nV/√Hz typical), high common-mode rejection ratio (CMRR), power supply rejection ratio (PSRR), and open-loop gain (Avo) (> 120 dB minimum).

Low supply current (400 μA per amplifier), dual supply operation (+2.5 V to +15 V), and unity-gain stability.

Inputs are internally protected beyond supply voltage, and outputs are stable with capacitive loads of over 1000 pF without external compensation.


Wireless base station control circuits, optical network control circuits, instrumentation, sensors and controls, thermocouples, resistor thermal detectors (RTDs), strain bridges, shunt current measurements, and precision filters.
